Description

  The present invention relates to a time difference output device, and particularly relates to a time difference pressure distribution output device.

  Taking bicycle brake control as an example, for example, a general bicycle brake device drives a brake to stop a front wheel and a rear wheel of a bicycle by being gripped by a user. In a general brake linkage configuration, the right brake handle controls the front wheel brake, and the left brake handle controls the rear wheel brake. In the case of a sudden stop, it is possible to accidentally brake the front wheels or simultaneously brake the front and rear wheels. Such an improper stopping operation of braking the front wheel may cause the rear wheel to float due to inertia and cause rollover or skidding. If the brakes are applied only to the rear wheels, it may not be possible to stop immediately due to insufficient braking force, and long-distance running may occur.

  Although the brake synchronization technology developed based on the above-mentioned drawbacks has already been commercialized, there is a possibility that the synchronized brake still brakes the front wheel and the rear wheel floats due to inertia, causing the bicycle to overturn or slip. Yes, the problem has not been solved reliably. A more accurate stopping method must stop the front wheel first, then stop the rear wheel, and the force applied to the front wheel must be stronger than the rear wheel. Therefore, by providing an output device capable of outputting a time difference, it is possible to effectively brake the user in the correct manner and prevent an accident.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. The corresponding description is merely an example of the embodiment of the present invention, and does not limit the embodiment of the present invention.
As shown in FIG. 1, the time differential pressure distribution output device 100 according to one embodiment of the present invention includes: a slip chamber unit 11, a pressurizing unit 12 connected to one side of the slip chamber unit 11, and the slip chamber unit. connected to the other end of the 11, and a pressure release unit 13 connected to the first actuating mechanism B3, located between the slip chamber part 11 pressing 12 and the pressure release unit 13 connected to the slip chamber part 11 and a time difference pressure release unit 14 connected to the second actuating mechanism B4, and inspired members B1, B2 to be connected to the pressing 12, a pressure chamber member 1 with a smooth state inside the slip chamber part 11 Pressure distribution that slips between the pressurizing unit 12 and the pressure releasing unit 13 by being installed at a distance between the pressurizing unit 12 and the pressure releasing unit 13 The pressure part 12 applies a pressure P0 to the slip chamber part 11 when the triggering member B1 is triggered, and the pressure distribution member 2 receives pressure to receive the pressure releasing part 13. by slipping into the pressure relief section 13 is given rise to operating pressure Pa1 with respect to the first operating mechanisms B3, is operated the first actuating mechanism B3, the pressure distribution member 2 is the slip chamber part 11 When the time difference pressure release part 14 slips to a position corresponding to the time difference pressure release part 14, the pressure part 12 is connected to the time difference pressure release part 14, and the time difference pressure release part 14 is connected to the pressure P 2 of the pressure part 11. by receiving the said second operating pressure Pa2 is generated relative to the second actuating mechanism B4, the time difference with respect to operation of the first actuating mechanism B3 together to run the second actuating mechanism B4 stick

  As shown in FIG. 1, in this embodiment, the time difference pressure distribution output device 100 is applied to the brake system of the bicycle B. The inspiring members B1 and B2 are the brake starters (that is, the front wheel brake handle and the rear wheel brake handle) of the bicycle B, the first operating mechanism B3 is the brake operating mechanism of the bicycle B (that is, the rear wheel brake), and the second operating mechanism B4. Is a brake operating mechanism (that is, a rear wheel brake) of the bicycle B.

  As shown in FIG. 1, in this embodiment, the pressure chamber 1 is a hydraulic chamber member, and the slip chamber portion is pressurized or depressurized by the movement of the hydraulic oil by being filled with the hydraulic oil. Of course, the present invention is not limited thereto, and the slip chamber 11 can be filled with a liquid other than hydraulic oil, or can be filled with gas. In this embodiment, the structure of the pressure chamber member 1 is the same as that of the T-shaped tube, and the tube between the pressurizing unit 12 and the pressure releasing unit 13 slips the pressure distribution member 2 smoothly into the tube. It is preferable to go straight.

  As shown in FIG. 1, in this embodiment, the pressure distribution member 2 functions as a piston in the slip chamber portion 11. The diameter of the pressure distribution member 2 is the same as the inner diameter of the slip chamber portion 11, and the slip chamber portion 11 is roughly divided into three chambers. That is, the first chamber 11a located on the pressurization unit 12 side, the second chamber 11b located on the pressure release unit side 13, and the third chamber 11c located on the time difference pressure release unit 14 side. The pressure P0 in the first chamber 11a is determined by the pressure input by the pressurizing unit 12 after the trigger members B1 and B2 are triggered. The pressure P1 in the second chamber 11b is determined mainly by a change in volume caused by the pressure distribution member 2 slipping and moving. The pressure P2 in the third chamber 11c is not influenced by the pressure distribution member slipping and moving, and is directly input by the pressurizing unit 12 in a state where the third chamber 11c is connected to the first chamber 11a. The pressure changes depending on the pressure.

Subsequently, an operation method of the time differential pressure distribution output device of the present invention will be described with reference to FIGS.
As shown in FIG. 2 a, when one or both of the triggering members B <b> 1 and B <b> 2 (FIG. 1) triggers, a signal S (for example: traction force of the brake wire) is transferred to the pressurizing unit 12. The pressurizing unit 12 applies a pressure P0 (for example: atmospheric pressure or hydraulic pressure) to the first chamber 11a of the slip chamber 11. As the pressure in the first chamber 11a increases, the pressure distribution member 2 slips to the pressure release portion 13 because the pressure in the second chamber 11b is relatively low. Accordingly, the pressure P1 in the second chamber 11b increases, and the pressure release unit 13 generates the first operating pressure Pa1 for the first operating mechanism B3 to operate the first operating mechanism B3. Start braking the wheel.

  As shown in FIG. 2 b, the pressure distribution member 2 continues to slip to the pressure release unit 13 in response to the pressure P0 input from the pressurization unit 12. When the pressure distribution member 2 slips to the position of the time difference pressure release part 14 corresponding to the slip chamber part 11, the pressurization part 12 is connected to the time difference pressure release part 14, that is, the first chamber 11a is connected to the third chamber 11c. Connect. In this case, the third chamber 11c gradually rises under the influence of the pressure P0 of the first chamber 11a, and the time difference pressure release unit 14 generates the second operating pressure Pa2 for the second operating mechanism B4, The second operation mechanism B4 is operated, that is, the rear wheel of the bicycle B is started to brake. As described above, the operation of the second operation mechanism B4 provides a time difference with respect to the operation of the first operation mechanism B3, so that the bicycle B brakes the rear wheel first and continues to brake the front wheel. Safe stop can be performed accurately. In the present embodiment, the slip chamber section 11 has an amplifying section 15, and the c-jumper cross-sectional area of the amplifying section 15 is the disconnection between the chambers at both ends of the slip chamber section (that is, the first chamber 11a and the second chamber 11b). Greater than area. When the time difference pressure release unit 14 is connected to the amplification unit 15 and the pressure distribution member 2 slips to a position corresponding to the time difference pressure release unit 14, the pressurization unit 12 is connected to the pressure distribution member 2 and the amplification unit 15. It connects with the time difference pressure discharge | release part 14 through the bigger clearance gap formed in between.

  In the present embodiment, the slip chamber part 11 further has a position restricting member 16, and the position restricting member 16 is installed on one side of the pressure releasing part 13 adjacent to the slip chamber part 11 and the pressure releasing part 13 and the pressure distributing member. Between the two chambers, i.e., in the second chamber 11b. The position restriction member 16 stops the pressure distribution member 2 at a predetermined position, so that the slip movement of the pressure distribution member to the pressure release unit 13 is restricted. It can be noted here that the position limiting member 16 has a passage port 161 or other ventilation structure so as not to block the flow of gas or hydraulic oil in the second chamber 11b. The position limiting member 16 is preferably installed so as to be adjustable. Thereby, the position where the pressure distribution member 2 is restricted by the adjustment is determined.

  More specifically, as shown in FIG. 2c, the pressure distribution member 2 receives the pressure P0 from the pressurizing unit 12 and continues to slip to the pressure release unit 13, and is caught by the position limiting member 16 to stop the slip. The In this case, the pressure P1 in the second chamber 11b does not increase any more, the first operating pressure Pa1 output from the pressure release unit 13 does not change any more, or the output is stopped by design. On the other hand, the pressure P2 in the third chamber 11c continues to increase due to the pressure P0 from the pressurizing unit 12, and continuously operates the second operating mechanism B4. In such a design, the first operating pressure Pa1 and the second operating pressure Pa2 can not only provide a time difference in output, but also can adjust the strength of the output pressure. Regarding the application of the bicycle brake system, there is a difference in timing when the first operation mechanism B3 and the second operation mechanism B4 start to operate (the brake is applied), and finally the force of the front brake is larger than the rear brake. Can be stopped completely. As a result, it is possible to prevent a situation in which the bicycle cannot be surely stopped due to a mistake in the amount of braking force applied to the front and rear.

  Subsequently, as shown in FIG. 2d, when the triggering members B1 and B2 are released (FIG. 1) and the signal is stopped, the pressurizing unit 12 stops the pressurization, and the pressure P0 of the first chamber 11a is lowered to the initial stage. Return to value. When the pressure P0 in the first chamber 11a falls below the pressure P1 in the second chamber 11b, the pressure distribution member 2 slips to the original position and moves to a position where the pressures on both sides reach equilibrium.

  As shown in FIG. 2e, when the pressure distribution member slips to divide the first chamber 11a and the second chamber 11c, a pressure imbalance occurs due to the pressure P2 in the third chamber 11c being larger than the first chamber. there is a possibility. Therefore, the pressure distribution member 2 preferably has a back pressure passage 21, and the back pressure passage 21 is extended so as to penetrate the pressure distribution member 2. Both ends of the back pressure passage 21 correspond to the positions of the time difference pressure release portion 14 and the pressurizing portion 12, respectively, that is, both ends of the back pressure passage 21 are connected to the third chamber 11c and the first chamber 11a, respectively. The pressure P2 of the time difference pressure release unit 14 is conducted to the pressurization unit 12 through the back pressure passage 21. In this embodiment, the back pressure passage has a plurality of passage sessions 211 a, 211 b, 211 c, and 211 d that are installed radially, and the openings of the passage sessions 211 a, 211 b, 211 c, and 211 d are at the position of the time difference pressure release unit 14. It is in the corresponding position, i.e. connected to the third chamber 11c. By providing a plurality of passage sessions 211a, 211b, 211c, and 211d, the pressure equilibrium between the third chamber 11c and the first chamber 11a is accelerated.

  In order to prevent an undesirable pressure leak due to the back pressure passage 21, the pressure distribution member 2 in the present embodiment further includes a valve 22. The valve 22 is installed in the back pressure passage 21, and the valve 22 is installed. The time difference pressure release part 14 is opened to the pressurizing part 12 in one direction. In other words, when the pressure P2 of the third chamber 11c is larger than the first chamber 11a, the valve 22 is opened, and the pressure is balanced by connecting the third chamber 11c to the first chamber 11a (FIG. 2e). When the pressure P0 of the first chamber 11a is larger than the third chamber 11c, the valve 22 closes the back pressure passage 21 to prevent the pressure of the first chamber 11a from leaking to the third chamber 11c through the back pressure passage.

  With the above-described structure, the time difference pressure distribution output device 100 according to the present invention can output an operating pressure having a time difference to the brake system of the bicycle B, and can safely stop the front wheels first and then stop the rear wheels. The stopping method can be performed accurately. Of course, the present invention is not limited to this, and the time difference output can be controlled by applying the time difference pressure distribution output device 100 to other devices. Further, the time difference pressure distribution output device 100 of the present invention generates an operating pressure by the pressure distribution member 2 slipping, and has a continuity of change of the operating pressure, thereby operating the actuator more smoothly, Reduce malfunction or instability due to sudden changes in output.

  The preferred embodiments of the present invention have been disclosed as described above so that those skilled in the art can understand them, but these do not limit the present invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the claims of the present invention should be construed broadly including such changes and modifications.
